The Madrague duo from NARS is a classic duo with a lighter color I use for under the brow bone and the darker all over the rest of the eyelid. This duo goes well with other NARS duos like Portobello to mix the colors or for a three color eye design. I own both.The duos come in a well made case that is about 2.75" by 2.125" and less the .5" thick. There is a mirror in the lid and the case shuts securely. I like the size because I can easily bring both when traveling and they are comfortable to hold while applying the eyeshadows. My only little complaint, and this is try for most NARS cosmetics packaging, is that the matte black case shows fingerprints easily so the cases don't remain great looking for long unless I wash my hands after applying primer and foundation.
